Foreign exchange prices reflect the relative value of two currencies. Observing interest rates, economic data and market sentiment can help understand the source of price changes.
Start with basic concepts
Market changes are often driven by a combination of factors. Understanding product structure, trading hours, and costs is more important than just looking at a single price.
Put risk before decision-making
There is uncertainty in any transaction. You should assess risks based on your own objectives, experience and financial situation and seek independent advice where necessary.
